Dreams

Every once in a while I start thinking about something and relate it in a conversation I am having with someone. But then I get this weird feeling that it never really happened, that I dreamed it. It's sort of weird, and it happens from time to time like this, where a dream I had manifests itself as a memory, and then I'm not sure if it actually happened or if I dreamed it. I've noticed it happens when I'm especially consumed with work, and am thinking about it more than I would like to. So my dreams start centering around work, and then in the morning or a couple days later I don't know if these things really happened or if I dreamed that they happened. It's kinda weird.
